I just finished sorting out the camber on the front end of the M3W. I got them both to about 1.3 degrees negative. I then checked the caster and found that the passenger side was 2 degrees negative and the driver's side is 5 degrees negative. Empire calls for 6 to 8 negative. The only possible way I see to adjust the caster is to move the two small washers both to one side allowing the heim joint to move backward. Is this the accepted adjustment?
